## Resource

We cover post-quantum cryptography (PQC) regularly on this show, focusing on the new math-based ciphers that will secure the Internet as quantum computing becomes more powerful. But what about physics-based encryption or quantum key distribution (QKD)? Is that still a thing? We examine how exploiting the laws of quantum physics can securely exchange encryption keys over a fiber and explore the benefits of the newer continuous-variable QKD. CVQKD leverages off-the-shelf telecom components for affordability, integrates with existing data networks, achieves higher key-generation rates, and reaches distances of up to 100 kilometers without requiring dark fibers. Real-world demos include securely linking hospitals in Madrid for remote consultations via Telefonica's network, and there could be a future where QKD devices are integrated into our home routers, democratizing quantum security.
